They better not be. They are often pushed directly to master, but that's different from force pushing (i.e., pushing a non-fast forward commit). As far as I can tell, this won't disable directly pushing without a pull request. Aaron Meurer On Fri, Sep 4, 2015 at 2:01 PM, Jason Moore wrote: > I'

I'm pretty sure that most "new author" commits are force pushed to master and when they aren't, i.e. use a PR, there is high likelihood of merge conflicts when there are other new authors. If we protect master, we'll have to deal with this. Jason moorepants.info +01 530-601-9791 On Fri, Sep 4, 2

2015-09-04 Thread Kalevi Suominen
It appears possible to compute the transform for ``zeta > 1`` by replacing ``zeta`` with ``1 + zeta``. In [22]: G = K/(tau**2*s**2 + 2*tau*(1 + zeta)*s + 1) In [24]: print(inverse_laplace_transform(G, s, t)) K*(exp(t*sqrt(zeta)*sqrt(zeta + 2)/tau) - 1)*(exp(t*sqrt(zeta)*sqrt(zeta + 2)/tau) + 1)

2015-09-04 Thread Francesco Bonazzi
You may assume variables to be positive/negative, for now. Sage uses a lot of backends. In case of *assume(zeta > 1)*, I believe it relies on Maxima, which can handle that kind of assumptions. SymPy's aim, on the other hand, is to implement all the algorithms on its own. Assumptions with inequ
